detail

gall

The larvae live each in an elliptic gall chamber in the sapwood under the bark of a somewhat older branch; the chambers lie more or less parallel to the surface. The bark swells, splits and frays; after the midges have emerged, parts of the sapwood and the gall chambers become exposed. Larvae greenish yellow. Univoltine,de larva hibernates, and pupates in spring just below the epidermis of the branch.
